Dr. Ruth Landau-Cahana
Virginia Apgar Professor of Anesthesiology and Chief, Division of Obstetric Anesthesia
As a clinician-scientist dedicated to helping women better endure labor pain and childbirth and improve neonatal outcomes, Dr. Landau has concentrated her efforts on investigating the influence of genetics on pregnancy-related disorders, such as preterm labor and delivery, endothelial dysfunction and preeclampsia, as well as labor pain and its relief, and the ability to predict one’s individual susceptibility to develop postoperative and chronic pain.
Dr. Landau is the Chief of the Division of Obstetric Anesthesia at Columbia, and leads the Center for Precision Medicine Research within the Department of Anesthesiology. She also is the immediate Past President of the Society for Obstetric Anesthesia & Perinatology (SOAP).
Dr. Landau is passionate about teaching, providing clinical care, and researching ways to improve patients’ experiences and care. She currently is invested in identifying clinical, genomic and epigenetic factors to predict and help prevent adverse perioperative outcomes in all age groups.
Clinical research within the Division of Obstetric Anesthesia involves RCTs aiming to improve provision of neuraxial labor analgesia and anesthesia for obstetric procedures (Dr. Allison Lee, Dr. Richard Smiley), as well as outcome studies in the field of high-risk obstetric patients using institutional databases (Dr. Laurence Ring, Dr. Richard Smiley) and national databases (Dr. Jean Guglielminotti).
Dr. Landau is leading the Columbia/NYPH Enhanced Recovery after Cesarean Delivery (ERACeD) program in collaboration with the Department of Obstetrics & Gynecology (Dr. Janice Aubey). The program investigates ways to promote judicious opioid prescription after cesarean delivery and raises awareness about the risks associated with excessive opioid use postpartum.
Dr. Landau has received NIH funding to investigate the epigenetic impact of in utero opioid exposure on Generation Z. The alarming rise in opioids prescriptions nationwide, including during pregnancy, has resulted in increasing numbers of neonatal drug withdrawals. Evidence has emerged that Neonatal Abstinence Syndrome (NAS) babies are more likely to become "addicted" later in life. This study explores the hypothesis that in utero opioid exposure results in epigenetic processes with potentially long-term consequences for the fetus/child such as an increased vulnerability to develop an opioid (mis)use disorder.

Current Precision Medicine Initiatives with the Institute of Genomic Medicine are evaluating:
- Post-cesarean pain – a multicenter project aiming at predicting acute pain and analgesic intake, as well as persistent and chronic pain, with psychophysical tests and genetic markers, in collaboration with Santa Joana Hospital, Sao Paolo Brazil, Stanford University, and Haifa University.
- Local anesthesia insensitivity – a project aiming to phenotype individuals’ responses to local anesthesia (Dr. Bridget Ferguson; College of Dental Medicine and Department of Oral & Maxillofacial Surgery) and evaluate genetic markers associated with resistance or insensitivity to local anesthetics.
- Uterine contractility - a project aiming at evaluating extreme phenotypes such as idiopathic preterm labor and non-contractility of the term uterus and to identify genetic markers (with Dr. Richard Smiley)
- Preeclampsia – several observational studies in an attempt to bridge the gap between obstetric health and long-term cardiovascular outcomes in women diagnosed with preeclampsia, assessing biomarkers, vascular reactivity and endothelial function with non-invasive measures (EndoPAT) in the postpartum period, in middle-aged women undergoing gynecological procedures, and later in life when requiring cardiovascular surgery (Dr. Andrea Miltiades).
- Post-operative delirium - a project aiming to identify genetic markers associated with post-operative delirium among elderly patients.
- Respiratory muscle paralysis after polymyxin B – a project aiming to identify genetic markers associated with this rare phenotype among ICU patients (Dr. Vivek Moitra).
Dr. Landau is collaborating with Dr. Kirsten Cleary (MFM Obstetrics), Dr. Eliza Miller (Neurology), Dr. Natalie Bello (Cardiology) in a Precision Medicine Pilot Award funded project (April 2018) evaluating maternal health after preeclampsia. Investigations include maternal cardiac, cerebral, and vascular monitoring for up to 12 months postpartum.
Other collaborations include:
1) a CTSA Pilot Award working with the Department of Epidemiology (Prof. Silvia Martins) to develop tools guiding individualized opioid prescriptions (January 2020).
2) an NIH grant funding the MFM-U Network to study an intervention individualizing opioid prescriptions with shared decision making after cesarean delivery - the Prescription After Cesarean Trial (PACT) in collaboration with Department of Obstetrics & Gynecology (Prof. Cynthia Gyamfi).
